14 A teacher gives her students a paper plate, glue, 10 black beads (electrons), 10 blue beads (neutrons) and 10 red beads (protons). The students are to glue the beads onto the
paper plate to construct an atom. One student chooses to construct Magnesium and finds
out that he doesn't have enough beads. How many more beads of each color does he need
to correctly construct the atom?
A.2 black, 2 blue, 2 red
B.1 black, 1 blue, 1 red
C.3 black, 2 blue, 1 red
D.3 black, 3 blue, 3 red

Rutherford's experiment indicated that matter was not as uniform as it appears what part of his experimental results implied this idea

Asolution is made by dissolving 2.3 moles of sodium chloride (nacl) in 0.155 kilograms of water. if the molal boiling point constant for water (kb) is 0.51 °c/m, what would be the boiling point of this solution? show all the steps taken to solve this problem.

Astudent made the lewis dot diagram of a compound as shown. mg is written with two dots shown on its top. an o is written on each side of mg. each o has six dots around it. an arrow is shown from one dot on mg toward the vacant space around the o on the right. another arrow is shown from the other dot on mg toward the vacant space around the o on the left. the title of the art is students lewis dot model. what is the error in the lewis dot diagram? an o atom should transfer all its six electrons to mg because the formula is mgo. both electrons of mg should be transferred to one o atom because the formula is mgo. the electrons should be transferred from each o atom to mg because mg has fewer electrons. the number of dots around mg should be four because it has to transfer two electrons to each o.
